a claims.

My invention relatesI to slug controlled fluid dispensing apparatus.

The object of my invention isto provide improved means which may be attached to the usual gasolene dispensing apparatus whereby the motorist may obtain a given amountby depositing a slug in a receptacle to control the operation oi an electric motor which drives the gasolene pump. A further object is to provide a signal such as' a bell or'buzze'r, or show a light during the time the pump is operated.

Afurther object is to provide a construction which will prevent the circuit from being closed except by the slug designed for the purpose, and other and further objects will appear from the following specincation.

Referring to the drawingwhich forms a part of this specification:

lFig. l is a front elevational view oi a filling 20l station pumpV incorporating my invention.

Fig. 2 is a front elevational view, partly in section, showing my improved chute and circuit controlling mechanism.

Fig. 3 is a vertical section of a portion of the V.255 chute in which a slug (in broken lines) is shown in circuit closing position.

Fig. 4 is a sectional view taken on lines 4 4 of Fig. 3.

Fig. 5 is a rear elevation of the portion of the chute shown in Fig. 3.

Fig. 6 is a View similar to Fig. 5 showing the support for the slug moved from its supporting position.

Fig. 7 is a sectional view of the special slug which I employ to control the pump circuit.

10 indicates a tank for gasolene, l1 a pump casing, 12 a pump and 13 a motor which drives the pump to deliver gasolene at the hose nozzle 14 in the usual manner.

15 indicates a pulley mounted on a shaft 16 of the pump clock, and driven by the motor thru the belt 17 in predetermined geared relation to register the amount of gasolene delivered at the nozzle 14.

Mounted on shaft 16 is a rotating switch actuating device comprising radial rods 18 which are spaced apart an equal distance from each other, the iree ends oi which act to operate the switch lever 19 successively to liberate a slug 20 from the 50-chute to break the motor circuit.

21 indicates the chute, the lower portion being made of electrical insulating material 22, while the upper portion is made of metal and is provided wth a receptacle 23 intol which the slug is 55v-deposited after lifting a swinging door 24 which closes therecepta'cle and serves to exclude dust, water etc. from the chute.

Mounted in the insulated portion 22 neanits upper end is a hinged door 25 or" conducting metal which normally extends across the chute passage and contacts a terminal 26, said doorbeing yieldingly supported in its normal position by a light spring' at its hinge 27. Astrip con-4 ductor 28 is held in the casing and extends down-V ward from hinge 27 and terminates in a Contact 29 exposed on the inner wall of the 'casing directly opposite a similar contact 3G located inthe casing and, in turn, connectedwith a terminal conductor 31 leading to the'mtor.v A conductor 32 is connected to the terminal26'and also 1leads to the motor'to complete a circuit therethru'whn the'slugis held in position a'ss'hov'vn'in Fi'g. '3.

The chute passage is increased in width at the point where the contacts 29 and 30 are located and said contacts are spaced apart far enough to prevent a slug that is not provided with expanding means, such as shown in Fig. 7, from closing the circuit. The chute 33 is of metal and is connected with the upper chute portion in open communication therewith to conduct the slug to a suitable safe receptacle.

The lever 19 extends across the casing 22 and is fulcrumed at 34 by a screw held on a supporte ing extension 35 fixed to the casing, and a spiral spring 36, one end of which is secured to the extension and the other end to the lever, serves to hold the lever in its normal position but permits it to yield when under pressure of a rod 18 which, as it moves past the end of the lever, trips it and actuates an attached lever 38 fulcrumed at 37. The lower end 38 of the lever 38 is bent and extends across the passage of the chute to support the slug in position to close the motor circuit.

The slug 20 is made of insulating material, is shaped substantially as shown, and is provided with a metal tube 39 which extends therethru from one side to the other as shown. Movable contact pieces are tted toy slide in this tube a limited distance, being held apart by a spring 40, and the contacts are each provided with a flange L11 which abuts metal plugs held tightly in the ends of the tube 39. The spring 40 is not strong enough to prevent the slug from dropping freely down the chute passage, but is strong enough to force the contact pieces outwardly to bridge the terminal contacts 29 and 30.

A signal 42 such as a bell, buzzer or light coupled in the motor circuit may be placed in a room of the attendant and will be operated during the etv sti

time the motor is running to indicate to the attendant the quantity of uid dispensed.

In operating the device, the motorist lifts the cover 23 and deposits a slug in the chute passage opening, the narrow portion being inserted to guide the slug into the chute, and the slug then slides down and contacts the upper side of the door 25, forcing it to swing downwardly into a recess formed, as shown, in one side of the chute. Immediately after the slug has passed the door, the door swingsV back to its normal closed position and contacts with the terminal 26, and when the slug has reached its lowest position in the insulated portion of the chute it will rest on the support 38 and the spring pressed contacts carried by the slug will slide outwardly and contact with the terminals 29 and 30, thus closing the circuit thru the motor.

The motor then drives the pump until a Arod 18 in its rotation contacts the lever 19 and releases the slug which, in dropping, breaks the circuit and the motor stops.

The purpose of the door 25 is to prevent a slug being held in the chute by a cord or other means in position to close the circuit. Any such device would prevent the door from closing and, therefore, the circuit would not be completed.

Although I have shown and described my apparatus as adapted to dispense gasolene, it will be obvious that it may be employed to dispense any fluid other than gasolene in measured quantities. t

Having thus described my invention, I claim:

1. A fluid dispensing device comprising an electric motor and a pump driven thereby, a chute adapted to receive and guide a slug, said chute having an insulated portion enlarged in width below its top and electric terminal contacts located at opposite sides of said portion, a slug having a movable switch element carried thereby which expands laterally to contact said terminals and complete a circuit thru said motor, means for arresting the slug in said chute in circuit closing position, and means operated by the motor to release the slug after a predetermined period of pump operation.

2. A fluiddispensing device comprising an electric motor and a pump driven thereby, a chute adapted to receive and guide a slug, said chute having an insulated portion enlarged in Width below its top and electrical terminal contacts located at opposite sides of said portion, a slug having a movable switch element carried thereby which expands laterally to contact said terminals and complete a circuit thru said motor, means for arresting the slug in said chute in circuit closing position, and means operated by the motor to releasethe slug after a predetermined period of pump operation; a ap door of conducting metal yieldingly hinged and normally extending across the chute above said contacts and in the same circuit therewith, and a terminal in'said chute against which said door contacts when in normal position, the arrangement being such that the motor circuit will be incomplete until the door has returned to its normal position.

3. A slug for use in actuating an electrically controlled dispensing device' comprising a body portion of insulating material and a movable switch element carried by said body portion, said switch element comprising expansible conducting means adapted to complete an electric circuit in the device.
